What is PolyDADMAC Powder CAS 26062-79-3?

PolyDADMAC is the solid form of poly(diallyldimethylammonium chloride), a high-charge-density cationic quaternary ammonium polymer. It is also known as PDADMAC, PolyDMDAAC, or Polyquaternium-6.

Why choose solid PolyDADMAC instead of a liquid polyDADMAC solution?

Liquid grades often contain only 20-50% active polymer and are mostly water, which raises freight cost and requires larger storage volume. The powder is a high-solids form, usually around 90% active content or higher, and is easier to ship and store in export markets.

Can PolyDADMAC Powder replace PAC or aluminum sulfate in water treatment?

In many coagulation and flocculation applications it can replace or partially reduce inorganic coagulants. PolyDADMAC works by charge neutralization and can produce less metal-hydroxide sludge than PAC or alum, while still improving color removal and sludge dewatering.

How should PolyDADMAC powder be dissolved before use?

It is soluble in cold water, but it should be added slowly under mixing to avoid fish-eyes or sticky lumps. A 1% solution typically has a pH of about 3.0-7.0, and the prepared solution is then diluted to the required dosing concentration.

What are the main industrial uses of PolyDADMAC CAS 26062-79-3?

It is used in water and wastewater treatment as a coagulant, sludge dewatering aid, and dye-wastewater decolorizer. It is also applied in papermaking as an anionic trash catcher and in textile processing as a cationic fixing or charge-control agent.

PolyDADMAC Powder CAS 26062-79-3

PolyDADMAC Powder CAS 26590-05-6 is a concentrated cationic quaternary ammonium polymer chemically defined as poly(diallyldimethylammonium chloride) , functioning primarily as a high-efficiency primary coagulant in potable water treatment and a charge-neutralizing agent in wastewater clarification. DADMAC is the quaternary ammonium monomer used to produce PolyDADMAC. Unlike standard liquid grades (typically 20-50% active), this solid bead or granular form offers 100% active content, utilized to destabilize negatively charged colloidal suspensions and reduce sludge volume in dewatering processes. We provide professional access to this material with competitive factory pricing and the ability to meet customized specifications (varying intrinsic viscosity levels) for various manufacturing requirements. Our commitment to technical transparency ensures that every shipment is accompanied by comprehensive MSDS, TDS, COA documentation to support your quality assurance protocols, and we maintain capacity for consistent bulk supply to facilitate large-scale industrial operations.

Applications

PolyDADMAC Powder is a versatile cationic polymer utilized in various industrial sectors:

1. Water & Wastewater Treatment:

Primary Coagulant: Destabilizes suspended solids and colloidal particles efficiently.
Sludge Dewatering: Enhances the filtration rate and cake dryness in belt presses and centrifuges.
Decolorization: Highly effective in removing color from textile dyeing wastewater and dye manufacturing effluents.

2. Paper & Pulp Industry:

Anionic Trash Catcher (ATC): Neutralizes interfering anionic substances in the wet end, improving the efficiency of other additives.
Retention & Drainage Aid: Increases the retention of fibers and fillers, speeding up the paper machine drainage.
Fixative: Improves the fixing of dyes and sizing agents to the fibers.

3. Textile Industry:

Fixing Agent: Used as a formaldehyde-free fixing agent for reactive and direct dyes, improving color fastness (wash and rub fastness).

4. Oilfield Chemicals:

Clay Stabilizer: Prevents clay swelling in drilling operations.
Water Clarification: Used in oil-water separation processes.

Quality Assurance (QA/QC)

Monomer Control (HPLC): We utilize High-Performance Liquid Chromatography (HPLC) to strictly monitor and minimize residual DADMAC monomer, ensuring the product is safe and environmentally compliant.
Molecular Weight Analysis: Gel Permeation Chromatography (GPC) is employed to verify molecular weight distribution, ensuring consistent flocculation performance batch after batch.
Impurity Screening: Every production run is tested for insolubles to prevent nozzle clogging in customer application systems.

For color-removal treatment programs that also require cationic water-treatment chemistry, see BWD-01 Water Decoloring Agent.

Storage, Handling & Safety

Storage Conditions:

Hygroscopic Nature: PolyDADMAC powder is highly hygroscopic. Store in a cool, dry place ( $< 35^{\circ} C$ <35∘C) in original, sealed packaging.
Shelf Life: 24 months from the date of manufacture if stored correctly. Ensure bags are re-sealed immediately after partial use.
Incompatibility: Avoid contact with strong oxidizers, iron, copper, and aluminum containers during solution preparation (use plastic, fiberglass, or stainless steel).

Safety Precautions (HSE):

Slip Hazard: Warning: Spilled powder becomes extremely slippery when wet. Do not flush spills with water initially. Shovel or sweep up dry powder first, then scrub the area.
PPE Recommendations:
- Respiratory: Wear a dust mask (N95/P2) to prevent inhalation of fine particles.
- Eyes: Use chemical safety goggles.
- Skin: Wear protective gloves and long-sleeved clothing to avoid prolonged skin contact.
